2.2 DRH Functions

This section describes the main functions of the DRH. The Distributed Remote Head (DRH) performs the following functions:



Receives downlink baseband data from the DCU and sends uplink baseband data to the DCU.



Receives RF signals from the antenna system, down-converts the signals to intermediate frequency (IF) signals, amplifies the IF signals, and performs analog-to-digital conversion. The transmit (TX) channel filters downlink signals, performs digital-to-analog conversion, and up-converts RF signals to the TX band.



Multiplexes receive (RX) and TX signals on the RF channel, which enables these signals to share the same antenna path. It also filters the RX and TX signals.



The DRH can be powered by the AC/DC power module. In this case, this DRH is called AC DRH.

An DRH consists of a high-speed interface unit, signal processing unit, power amplifier, and dual-duplexer. Figure 2-3 shows the logical structure of the DRH.

CPRI fiber optic cables are classified into multi-mode fiber optic cables and single-mode fiber optic cables. They transmit CPRI signals.

Exterior



An ODF can be used when the distance between a DPC and an DRH or the distance between interconnected DRHs is longer than 100 m (328.08 ft).



A single-mode fiber optic cable connects a DPC to an ODF or connects an ODF to an DRH.

Figure 3-5 shows a fiber optic cable between a DPC and an DRH or between DRHs, with a

DLC connector at each end.

Figure 3-5 Fiber optical cable between a DPC and an DRH or between DRHs

When a fiber optical cable connects a DPC and an DRH, the optical fibers on the DPC side and DRH side are 0.34 m (0.013 in.) and 0.03 m (0.0012 in.) long, respectively. When a fiber optical cable connects two DRHs, the optical fibers on both DRH sides are 0.03 m (0.0012 in.) long.

Figure 3-6 shows the connections for a CPRI fiber optic cable between a DPC and an DRH.

3.6 DRH RF Jumper

The 1/2" DRH RF jumper transmits and receives RF signals between an DRH and an antenna. A fixed-length RF jumper used by an DRH is 2 m (6.56 ft), 3 m (9.84 ft), 4 m (13.12 ft), 6 m (19.68 ft), or 10 m (32.81 ft) long. A variable-length RF jumper used by an DRH has a maximum length of 10 m (32.81 ft).

If the customer prepares the RF jumper, the length of the RF jumper should be as short as possible and not exceed 2 m (6.56 ft).

Exterior

An RF jumper has a DIN male connector at one end and a customized connector at the other end.

Figure 3-9 shows an RF jumper with a DIN male connector at each end.

5.1 U.S.A Regulatory Compliance

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:



This device does not cause harmful interference.



This device must accept any interference received, including interference that may cause undesired operation.

If this device is modified without authorization from Huawei, the device may no longer comply with FCC requirements for Class B digital devices. In that a case, your right to use the device may be limited by FCC regulations. Moreover, you may be required to correct any interference to radio or television communications at your own expense.

5 Appendix

This device has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.

This device generates, uses and radiates radio frequency energy. If it is not installed and used in accordance with the instructions, it may cause harmful interference to radio communications.

However, there is no guarantee that interference will not occur in a particular installation. If this device does cause harmful interference to radio or television reception, which can be determined by turning the device off and on, the user may take one or more of the following measures:



Reorient or relocate the receiving antenna.



Reinforce the separation between the device and receiver.



Connect the device into an outlet on a circuit different from that to which the receiver is connected.



Consult the dealer or an experienced radio or TV technician for assistance.

même temps qu'aucune autre antenne ou émetteur.La distance d’installation et d’opération entre le radiateur et votre corps de chaque équipement doit être au minimum :

Pour DRH3926A, 2.01m ou plus.

Some Information

(a) The nominal passband gain is 37dB; (b) The nominal bandwidth of band 2600M (DRH3926A)is 73.07MHz; (c) The rated mean output power is 2*20W; (d) The input and output impedance are 50Ω; (e) The following notice:”The Manufacture’s rated output power of this equipment is for

single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device.”
